According to this post Pro Wrestling Noah has been bought by rival company New Japan Pro Wrestling:
So apparently I've been told that Super Crazy did an interview where he confirms NJPW has bought NOAH and Jado is booking it now

This would add to the dominance that New Japan Pro Wrestling has over the Japanese market and to furthering the expansion of the company.
As of the writing of this, it is just a rumour right now but if this is true, this will change the shape of pro wrestling globally. Think of WWE buying WCW back in 2001, that would be the closest comparison and would be the biggest acquisition since.
Pro Wrestling Noah has been famous for wrestlers such as NXT star Hideo Itami (formerly known as KENTA), Kenta Kobashi, Naomichi Marufuji and the late Mitsuharu Misawa (who founded the promotion in 2000).
